ruby代写: COSC2675 Rapid Application Development

• ●  RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a “gem”).
• ●  In part 1, you need to install two gems, which are required for other parts of Assignment 1. You may use other relevant gems.

●

●

nokogiri

o https://github.com/sparklemotion/nokogiri

ruby-lint

o https://github.com/YorickPeterse/ruby-lint

• ●  You will need gem to make a useful command line application.
• ●  Write a script called

nokogiri

o e.g. is your student id, so name your file

s3123456

{:your_student_number}_p2.rb

s3123456_p2.rb

● When the script is called >>

ruby s3123456_p2.rb

, its output should look like:

Commands:
s3123456_p2.rb -xml [filename] # Load a XML file
s3123456_p2.rb help [COMMAND] # Describe available commands or one specific command

● Extracting time information from plain text such as emails is a very useful functionality, but still remains as a challenge. You can see examples in Gmail. Gmail underlines date and time in attempt to create calendar events automatically. As you can see, the result is often mixed. There are many scenarios that Gmail cannot handle well. Your task here is to write a script to achieve similar and even better performance than Gmail event extractor.

An XML file “emails.xml” will be provided which contains several emails. Below is an example email which shows send, date/time, subject, utc time and the body:

<record>
<id>17</id>
<first_name>Vern</first_name> <last_name>Dabernott</last_name> <email>vdabernottg@theguardian.com</email> <gender>Male</gender> <ip_address>155.168.41.66</ip_address> <send_date>2017-06-20T18:49:03Z</send_date> <email_body>1;DROP TABLE users</email_body> <email_title>real-time</email_title>

</record>

● Your Ruby program is expected to extract all the information for each particular record

● Your Ruby program should not crash or exit at any point given the input record is invalid or malformed

● Your Ruby can accept keyword search for ip address and return records in JSON format

s123456_p3.rb

ruby –ip 10.10.10.10

{ “id”: 2,
“first_name”: “Morgen”,
“last_name”: “Woolbrook”,
“email”: “mwoolbrook1@google.co.jp”, “gender”:
“Female”,
“ip_address”: “10.10.10.10”, “send_date”: “2018-01-27T14:27:06Z”, “email_body”: “􏱄􏱅􏱆􏱇􏱈􏱉􏱊􏱋􏱌􏱆􏱍”, “email_title”: “web-enabled”
},

…
…
…
… # to continue until the end

list

● Your Ruby can accept keyword search for name and return records for email_body corresponding email records.

s123456_p3.rb

ruby –name Alex

{ “id”: 102,
“first_name”: “Alex”,
“last_name”: “Louey”,
“email”: “alex.louey@google.co.jp”, “gender”:
“Female”,
“ip_address”: “100.212.3.12”, “send_date”: “2018-01-27T14:27:06Z”, “email_body”: “ghost in the shell”, “email_title”: “watch now!”
},

…
…
…
… # to continue until the end

list

The search is always case insensitive.

• ●  The “before” and the “after” can be combined or used separately. If the “before” time is earlier than the “after” time, then an error message will appear.
• ●  In addition, the script also supports days (such as Wed, wed, Wednesday, wednesday … )

o must be at least 8 characters
o must include at least one number
o must include at least one letter
o your script always needs an api-key

o if you provide any invalid api key, your script should terminate immediately

ruby s3123456_p4.rb –api-key=”alex’key” Invalid API Key, operation abort…

list

● If any valid is provided, then your script should read through the xml file and list the first 20 entries in JSON format.

api-key

ruby s3123456_p4.rb –api-key=”124FAfg$11s”
